| dc.description.abstract | The spatia1 distribution of eggs and larvae is a function of the properties
of the ambient water, i.e. the density, current and turbulent
diffusion, and of the physical properties of the eggs, i.e. the buoyancy
and dimension. The study of the vertical distribution is the
first step to understanding the horizontal transport of eggs and
larvae. Two models for the vertical distribution of eggs are applied
to demonstrate how the physical and biological conditions influence
the vertical distribution for the three main categories of eggs, here
defined as pelagic, bathypelagic and bottom eggs. In particular, the
physical conditions affecting the distribution of bathypelagic eggs
are studied. The wind induced turbulence is the most important ambient
factor for the vertical distribution of pelagic eggs and larvae. It
contributes to mixing the buoyant eggs and larvae through the wind
mixed layer. The vertical spreading of bathypelagic eggs depends
mainly on the buoyancy distribution of the eggs. It is demonstrated
from the model results that non-adhesive demersal eggs will be partly
mixed into the water column. This mechanism contributes to the
horizontal transport of demersal eggs. | en_US |
